Gardeners' Notes:

I've been growing a potted Celadine outdoors since 1998. After planting a young one outdoors in ground last summer,I see they do much better,stand up to cold better. Even though the bay area is considered much too cold,it can be done with care to planting in fast draining or a raised area, some protection if a hard below 32f cold comes along. I have heard of one that is over 10' in the east bay. My 4x4 potted plant could be that size if I had planted it. The key is-full sun,all year. They wont take any shade here. The best location could be those brick planters up against a sunny ,hot southwest facing exposure. Think hot,no hot is too hot for them here!.
One thing I have noticed about Plumeria here is they tend to bloom every other year. A year of lush leaf growth will end in flower buds....the next year it tends to bloom with minimal growth.
Plumeria may not be a strong grower here or a large plant-but even in a dwarf size they can be a focal point..and the late summer(here)blooms live up to the reputation.

I have had to re pot Celadine this spring (2013) due to major limb loss and it seemed on the edge of collapse. I think the main cause is soil chill. Since they seem to do well in pots here,plants in ground can't seem to put up with chill clay soils. Others might have try...but make sure they get full sun in winter. Right down to the soil.

Celadine is very popular cultivar and ranks at the top of the list of all plumeria flowers for fragrance. The scent is of sweet classic plumeria. Celadine can be distinguished from other cultivars not only by the flower's color and shape by the leaves, which are double veined at the rims. Cuttings root very easily, and the tree is easy to grow.
